EP1INT — Endpoint 1 Interface number
This bit specifies the interface number for physical endpoint 1. The interface number is loaded to the
USB module at the time when the USB module is enabled. When USBEN is set, this bit has no effect.
Reset clears this bit.
1 = The interface number for endpoint 1 is one
0 = The interface number for endpoint 1 is zero
EP2INT — Endpoint 2 Interface number
This bit specifies the interface number for physical endpoint 2. The interface number is loaded to the
USB module at the time when the USB module is enabled. When USBEN is set, this bit has no effect.
Reset clears this bit.
1 = The interface number for endpoint 2 is one
0 = The interface number for endpoint 2 is zero
EP3INT — Endpoint 3 Interface number
This bit specifies the interface number for physical endpoint 3. The interface number is loaded to the
USB module at the time when the USB module is enabled. When USBEN is set, this bit has no effect.
Reset clears this bit.
1 = The interface number for endpoint 3 is one7
0 = The interface number for endpoint 3 is zero
EP4INT — Endpoint 4 Interface number
This bit specifies the interface number for physical endpoint 4. The interface number is loaded to the
USB module at the time when the USB module is enabled. When USBEN is set, this bit has no effect.
Reset clears this bit.
1 = The interface number for endpoint 4 is one
0 = The interface number for endpoint 4 is zero

These are the IN/OUT data buffer endpoint 0. The OUT buffer can be accessed by reading to the
registers. The IN buffer can be accessed by writing to the registers.
